Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 103,032,127, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 103,032,127 | |
| -1 | -103,032,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,032,127.
Example:
1 x 103,032,127 = 103,032,127
and
-1 x -103,032,127 = 103,032,127
Notice both answers equal 103,032,127
With that explanation out of the way, let's continue. Next, we take the number 103,032,127 and divide it by 2:
103,032,127 ÷ 2 = 51,516,063.5
If the quotient is a whole number, then 2 and 51,516,063.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,032,127 | |
| -1 | -103,032,127 |
Now, we try dividing 103,032,127 by 3:
103,032,127 ÷ 3 = 34,344,042.3333
If the quotient is a whole number, then 3 and 34,344,042.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,032,127 | |
| -1 | -103,032,127 |
Let's try dividing by 4:
103,032,127 ÷ 4 = 25,758,031.75
If the quotient is a whole number, then 4 and 25,758,031.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 103,032,127 | |
| -1 | 103,032,127 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 73 | 341 | 803 | 2,263 | 4,139 | 24,893 | 45,529 | 128,309 | 302,147 | 1,411,399 | 3,323,617 | 9,366,557 | 103,032,127 |
| -1 | -11 | -31 | -73 | -341 | -803 | -2,263 | -4,139 | -24,893 | -45,529 | -128,309 | -302,147 | -1,411,399 | -3,323,617 | -9,366,557 | -103,032,127 |
